Tips For The Maintenance Of Mirror Rollers

The durability of the mirror roll has a very close relationship with the actual material and material selection, the internal structure combination design, the processing technology determination, and the heat treatment process. I want the mirror roll to have a longer life, which is inseparable from the usual maintenance.

Maintenance method of mirror roller:
1. The roller blank is made of professional imported alloy steel, and the material quality of the difference is different.
2, the mirror roller is usually selected from steel, alloy steel seamless pipe, precision forgings and other materials, the appearance of the roller can reach the finish level of 14;
3, can be mirror-finished in the appearance of various materials, to ensure the flatness, balance, out-of-roundness, coaxiality and other requirements of the appearance of the roller;
4, mirror roller cooling or heating temperature difference is not more than 1 ° C, appearance hardness HRC55 ~ 58, chrome polished hardness HRC62, thermal deformation is not more than 0.01mm.

 Under normal circumstances, when the mirror roller is installed in the rack, it will not be arbitrarily removed, which can extend the service life of the mirror roller. The most scientific method is to release the oil or water from the mirror roll and then pass the mirror roll into the rust-proof oil. When you want to use it, release the large mirror roller from the oil category, remove the oil and clean it, then use it in the normal way.



What are the classification of mirror roller polishing?

Mechanical mirror polishing is a smooth, shiny mirror-like surface that has been subjected to a buffing process (rough grinding, fine grinding) and a polishing process on a metal material.

Chemical Solution Mirror Roll Polishing is performed by immersing in a chemical solution to remove surface oxide scale to achieve a brightening effect.

Mechanical mirror roll polishing is performed on a metal material by a buffing process (rough grinding, fine grinding) and a polishing process (three-step polishing) to achieve a smooth, shiny mirror-like surface.


First, the polishing process

The purpose of polishing is to obtain a smooth and smooth surface. At this time, there is a very fine and uniform wear scar on the grinding surface. Polishing is divided into rough grinding and fine grinding.


1. Rough grinding Rough grinding is the modification of rough surfaces and irregular shapes.


2. Fine grinding After rough grinding, the metal surface still has deep wear marks, which need to be eliminated in the fine grinding to prepare for polishing.


Second, the surface polishing process

The polishing process is to obtain a glossy mirror-like surface finish. Most of the polishing wheels are used to repeatedly polish the extremely uneven surface on the surface of the part, which is commonly used for the modification of the surface of the coating.

Polishing is the final step of the surface of the coating or the surface of the part. The purpose is to eliminate the fine grinding marks remaining on the surface after the polishing process. The ideal polished surface should be a smooth, shiny, non-marking, embossed, pit-free, metal-free surface that is mirror-like. After grinding and polishing, the grinding surface changes.
The three-step mirror polishing is a polishing power tool which is used in combination with three kinds of polishing materials such as composite louver disc, synthetic grinding disc and wool strip polishing disc for mirror polishing. The polishing process is composite louver disc, synthetic grinding disc, and the surface polishing process is wool. Polished disc.


The first step: compound louver

The structure of the composite louver disc combines a surface-finishing material with a coated abrasive to remove rough surfaces and irregular shapes for rough grinding and preliminary fine grinding.


Step 2: Synthetic grinding disc

The highly concentrated abrasive is distributed over a sturdy non-woven base material to remove the glare or burrs on the stainless steel surface for fine grinding and preparation for polishing.


The third step: wool polishing disc

The wool strip has good flexibility and is easy to accelerate air flow cooling. It is suitable for polishing wax or paste to achieve the final procedure of the bright mirror-like metal surface processing.
